HAY-PRESS.

Specification of Letters Patent.

Patented Dec. 14, 1915.

Application filed July 21, 1914. Serial No. 852,266.

To all whom it may concern:

Be it known that I, IRA C. RUST, a citizen of the United States, residing at Farmland, in the county of Randolph and State of Indiana, have invented a new and useful Hay- Press, of which the following is a specification.

This invention has reference to improvement in hay presses, and is designed to produce a machine for the purpose containing a minimum amount of material in its construction to thereby reduce the cost of manufacture and weight without sacrifice of strength or durability and, furthermore, permitting the operation of the machine with materially less power than other machines for the purpose.

In accordance with the present invention the frame of the machine is made of angle steel, and may consist of four appropriately spaced L beams mounted directly upon suitable trucks with the spacing connections between the L beams forming material parts of the working structure and serving other purposes than that of bracing.

The press boX or chamber is provided with a plunger or follower controlled by a guided nut in turn driven by a screw located in the longitudinal center line of the frame of the machine. This screw is mounted for rotative movements, but is held against longitudinal movement and has fast thereto at one end concentric gear wheels engaged by oppositely arranged pinions controlled by clutches for connecting one or the other of the pinions to a drive shaft, so that the compression stroke is performed at a speed per mitting the application of great power, while the return or idle stroke may be at relatively great speed.

The invention also includes a packing structure connected to and operated by the follower feed nut in such manner as to give at a relatively long period of inactivity. Mounted on the baling chamber is a division board receptacle movable into and out of operative position, and when in operative position in the path of a member of the packer, so that the latter at proper intervals will cause the introduction of the division boards.

The invention also comprises other features which will appear from the detailed description to follow.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings :Figure 1 is a side elevation of a baler constructed in accordance with the present invention. Fig. 2 is a vertical longitudinal section through the driving end and a portion of the baling chamber drawn on a larger scale than Fig. 1 and showing some parts in elevation. Fig. 3 is an elevation of the driving mechanism as viewed from the left hand end of Fig. 2.

Fig. 5 is an elevation of one of the clutches with the shaft upon which it is mounted shown in crosssection. Fig. 6 is a section on the line 66 of Fig. 5 with some distant parts omitted. Fig. 7 is a section on the line 77 of Fig. 5, some parts being shown in elevation. Fig. 8 is an elevation of one of the latches and its spring employed on the baling chamber. Fig. 9 is a section on the line 9 9 of Fig. 8. Fig. 10 is a longitudinal section of the division board receptacle. Fig. 11 is a detail plan view of a portion of the clutch operating mechanism. Fig. 12 is a detail section of a guard for the baling chamber.

Referring to the drawings, there is shown a main or body frame made up of four beams 1, 2, 3, a, the beams being of structural steel, and in the particular showing of the drawings, of angle or L form with the outermost webs upright and the other webs substantially horizontal and directed one toward the other. The beams are in sub stantial parallelism. and at about midway of their length carry a baling chamber 5, the walls of which are made of sheet steel of appropriate gage to withstand the internal pressure due to the baling operation, and also to connect and brace the beams 1, 2, 3 and 4 constituting the longitudinal corner or edge members of the main frame. Near what may be termed the front ends of the beams 1, 2, 3 and 1 they are connected to the extremities of arms 6 branching outwardly from a central portion or hub 7, which latter, together with the arms, constitutes a spider. The arms 6 are curved both outwardly and forwardly and are of web and flange construction for strength and lightness, and are expanded at the extremities in the direction of the length of the re spective beams 1, 2, 3 and 1. The arms 6 are connected to the beams by bolts 8 extending through slots 9 in the webs of the arms, thus permitting lengthwise adjustment of the spider for a purpose which will hereinafter appear. The adjustment is facilitated by the employment of brackets 10 made fast to the respective longitudinal beams, and these brackets carry set screws 11 hearing against the flanges of the arms 6.

The spider made up of the arms 6 and hub is interior to the main frame of the machine, while exterior thereto at the same end of the machine are other arms 12 and 1 3 The arms 12 expand from a journal bearing 11 and at their extremities are connected to the outer faces of the upright webs of the beams l and 2. The arms 13 expand from a'journal bearing 15 and at their outer ends are connected to the upright webs of the main frame beams 3 and 4, respectively.

The journal bearings 11 and 15 are in alinement and carry a shaft 16 extending transyers ely of the corresponding end of the machine, intersecting the longitudinal Center line of the mainframe. The shaft 16 carries a main pulley 17 by means of which power is applied to the shaft through the intermediary of a belt, as is customary, but it will be understood that power may be applied to the shaft 16 in any suitable manner.

Between the interior spider joining the main longitudinal beams of the machine and the baling chamber, but quite close to the spider is a journal bearing 18 having its longitudinal axis' in the longitudinal center line of the machine and in turn supported upon an arch 19 connected to and rising from the lower beams 2 and 4 of the main frame. Mounted in the j ournalbearing 18 is a shaft 20 extending longitudinally of the in the longitudinal center line thereof. n the side of the journal bearing 18 toward the baling. chamber 5 the shaft 20 is screw threaded, as shown at 21, and in order to provide ample engaging surface without reducing the pitch of the threads to too great an extent. the threaded portion21 is doubly threaded.

The shaft to, the front of the bearing 18 is of reduced diameter, as shown at 22, and thererec eives the hub 23 of a gear. wheel 24, this gear. wheel being a bevel gear wheel with concentric series of gear teeth 25, 26, respectively, the outer gear teeth 25 being axially in advance of the inner gear. teeth 26.

The reduced end 22 of the shaft 20 projects axially through and beyond the toothed face of the gear wheel, and there carries a collar 27 which may be of suitably hardened steel, while the hub 7 is formed on the face toward the gear wheel 21 with a cup 28 housing a wear plate 29, between which and the collar 27 there is lodged a series'of anti-friction balls 30, designed to take up the thrust of the shaft 20, as will hereinafter appear. The hub 23 is connected to the shaft/extension 22 by a pin 31, so that the gear wheel and shaft will rotate together, but this pin is purposely so proportioned that should an extraordinary load be put upon the machine the pin will shear before the load increases to destructive proportions.

Mounted on the shaft 16 are bevel gear pinions 32, 33, respectively, the pinion 32 being in mesh with the gear 25, and the pinion 33 being in mesh with the gear 26, and because of the greater axial extent of the gear 25 the pinion 32 is of less diameter than the pinion 33. The pinions 32 and 33 are normally loose upon the shaft 16, but are prevented from movement one toward the other along the shaft by set collars 34,.

Mounted on the shaft 16 are clutches 35, 36, respectively, the clutch 35 controlling the pinion 32 and the clutch 36 controlling the pinion 33. The structure of these two clutches is substantially identical, and hence a description of one will apply to both, for

which reasei'r similar parts of the two clutches where appearing are designated by the same reference numerals. The description of the structure of the clutch will be apparent from Figs. 5, 6 and 7 in conjunction with Fig. 3. It will be considered that in Figs. 5, 6 and 7 the'clutch 35 is shown. The clutch is provided with a circumferential'fiange 37 projecting from one face of a disk 38, and this disk is provided with a hub 39 fast on the shaft 16, the hub abutting against the journal bearing 11; or 15, as the case may be. On the shaft 16 and extending into the flanged portion of the rotatable member of the clutch is a sleeve 1O having at one end a recess 11 into which enters a tongue -12 formed on the corresponding portion of the pinion 32 or 33, as thecase may be, so that any rotative movements of the sleeve 40 are participated in by the pinion 32.

'Mounted on the sleeve 10. so as to move lengthwise thereof is a collar 43 provided llu near one end with a peripheral groove 4A, 1

tral portion 19 which may be of hexagonal or other suitable shape for the application of a tool. That end of the screw 48 remote from the block 17 is threaded into a similar block 50 having trunnions 51.journaled in spaced ears 52 formed on a curved plate 53 carrying a similar curved friction facing 51 adapted to engage the inner wall of the flange 37. Oifstanding from opposite sides of the sleeve 10 are pairs of arms 55 ter1ninating in pins 56 entering sockets 57 in bosses 58 formed on the respective plates these arms serving to hold the plates, which together with the facings 51, constitute clutch shoes, within the flanges 37 against movement axially with relation to the clutch. If, now, the collar 13 be moved lengthwise of the sleeve 10, the blocks 17 and 50 being held in fixed relation one to the other by the screw 18 will rock on their journal pintles in the respective ears, thus causing the clutch shoes to approach and engage or recede and disengage from the inner walls of the flange 37, the movement of the clutch shoes toward and from the flange being guided by the pins 56.

To bring about the desired movements of the clutch shoes there are provided yokes 59, one for each clutch, and each yoke is formed on the corresponding end of a respective lever 60 or 61 pivotally supported in re spective brackets 62 and 63 made fast to the beams 1 and 3, respectively. Each yoke 59 carries pins 61 entering the respective groove 11 so that on a rocking of the lever the collars 4:3 are moved along the sleeves 40. The arrangement is such that both col lars move in the same direction at the same time, and as the clutches are oppositely arranged one clutch will go into action as the other clutch goes out of action. The arms of the levers 60 and 61 remote from the yokes are joined by a connecting rod or bar 65 which may be threaded at the ends for adjustment, or may be otherwise arranged for adjustment.

The lever 60 is provided with a continua tion 66 connected by a link 67 to one end of abell cranklever 67 on a bracket 67", the other end of this lever being connected to a reach rod 68 best shown in Fig. 1, and this reach rod is continued to a point adjacent to the baling chamber 5 where it is pivotally connected to one end of a manipulating lever 69 upstanding to a point where it may be within easy reach of an operator, and this lever is shown as provided with a ball or enlargement 70 tending to hold it by gravity in the active position. The reach rod 68 has adjustable stop blocks 71 and 72 thereon for a purpose to be described.

Mounted on the threaded portion 21 of the screw shaft 20 is a threaded block 73 from which extend arms 74 each carrying at its outer end a roller 75 positioned to taking the weight of the follower from the .screw shaft. 1

The block 7 3 is provided with cars 79 between which is pivoted one end of a rod 80, the other end of which enters an elongated frame 81. That .end of the frame 81 remote from the end entered by the rod has a head 82 to which is pivoted one end of a bar83, and the other end of this bar is hung upon a pin 81 extending through ears 85 on the upper ends of respective standards 86 rising from the beams 1 and 3 and approaclr ing as they rise, so that the bar 83 is midway of the width of the main frame. Fast to the bar 83 near its pivot support 81 is one end of another bar 87 connected at a point spaced from the bar 88 to a brace 88 in turn connected to the bar 83 near the frame 81. This arrangement provides a rigid frame movable about the pin 81 as a pivot, and the bar 87 is of a length to overhang the baling chamber at the free end of the bar where said bar has an angle continuation 89 to which fingers 90, 91 are secured, these fingers diverging and are held in spaced relation by a connecting bolt 92 carrying a spacing sleeve 93 between the fingers. Fast to the finger and projecting toward the rear of the machine is a bracket 94 for a purpose to be described.

The rod 80 within the frame 81 is surrounded by a spring 95 one end of which engages that end of the frame 81 through which the rod 80 enters the frame and at the other end the spring abuts against an adj usting nut 96 on the rod. The end of the rod carrying the nut 96 normally engages the head 82 at the corresponding end of the frame 81.

The lever made up of the members 83 and 87 with the fingers 90 and 91 constitutes a packer for feeding hay into the baling chamber through the open upper end thereof in advance of the retracted follower. To the rear of the position assumed by the follower when active in the baling chamber, the top of the baling chamber carries appro priate journal blocks 97, in which trunnions 98 are journaled. Adjacent to the journal blocks the trunnions carry brackets 99 in turn carrying a plate 100 having end por tions 101 in forward angular relation to the plate, while the edges of these end portions remote from the plate are returned one toward the other as shown at 102, thus forming an open ended receptacle into which division boards may be placed. One end of the receptacle carries spring fingers 108 each terminating in a latch member 10% of sufficient size to engage and retain a division board, but readily yieldable to a force somewhat greater than the weight of the board, so that the board may be easily ejected from the receptacle. Goacting stops 105 and 106 on the journal blocks 97 and brackets 99, respectively, engage when the receptacle is moved to an upright position, thus prevent ing the receptacle from overriding such position. A treadle 107 on one trunnion 98 forms a conveying means for moving the receptacle from a normally horizontal position to an upright position, these two positions being best shown in Figs. 1 and 2.

Extending across the hay receiving opening on top of the baling chamber is a plate 108 having an upturned nose portion 109 and recessed along the other edge as shown at 110. The plate is carried by a spring 111 which may be of the leaf spring type and of suitable length to yield as desired, the spring being connected at one end to the plate 108 and at the other end to the top of the baling chamber. The plate 108 serves as a guard for hay being pressed into the baling chamber preventing it from catching on the mouth of the baling chamber and yieldable to a mass of hay being compressed, the recessed portion 110 permitting the plate to enter into the baling chamber for a short distance. 011 the sides of the baling chamber clips 112 are applied, and each clip serves as a pivot support for a latch finger 113 extending rearwardly of the baling chamber and provided with a nose portion 114 entering the baling chamber through an appropriate passage 115. A U spring 116 engages the free end of the latch by the yoke portion of the spring, while the legs of the spring are held by the clip 112 to the baling chamber, the clip being suitably recessed for the purpose. The latches serve to prevent return of the compressed hay on the retraction of the plunger.

At the discharge end of the press the frame members 1, 2, 3 and at are engaged by a U-shaped yoke member 117 with the legs traversing a bar 118 and suitably threaded for the application of nuts 119, each of which may be provided with a handle 120, so that the corner beams of the frame may be caused to approach to reduce the efiective size of the discharge end, and thus regulate the amount of pressure applied in baling. The frame is supported upon front wheels 121 and rear wheels 122, so that the baler may be transported from place to place as is customary.

In the structure described it is unnecesx sary to make any part shown of any other material than steel, some of the structures being of structural steel, and others of cast or forged steel, and still others of sheet steel, and only a small amount of' machining is necessary. The arrangement is such that the structure is particularly durable, may be made at a comparatively low cost, and is capable of compacting hay to the minimum thickness'of bale without danger of injury to any parts. 1

The baler may be controlled as desired-to operate at will, or it may be readily released to automatic action. Let it be assumed that in the position of the parts shown in Fig. 1 a suitable quantity of hay has been introduced into the baling chamber by the self feeder, and that power is being applied to the main drive shaft 16. In the position shown the lever 69 has been moved to bring the clutch 35 into action, thus causing the pinion 32 to rotate and drive the screw shaft 20 in the proper direction to feed the nut 73 along it, so as to force the follower 77 into the baling chamber. As this movement starts the rod engaging the frameend 82 causes the feeder lever to rock on the pivot 81 to carry the fingers and-91 out of the baling chamber, the receptacle 100 having in the meantime been rocked by the operator to the horizontal position and'at an appropriate time a division board is placed therein. As the nut block 7 3 is fed to the rear by the screw shaft the self feeder is raised to a high position well out of the way and remains in such high position for the greater portion of the travel of the follower. Ultimately one of the arms 74 or any other traveling part of the structure is brought into engagement with the stop block 72, causing the rod 68 to then travel lengthwise of the machine with the follower and parts traveling with it until the lever 69 is rocked on its pivot away from its position toward the reverse position, this causing the opening of the clutch and the closing of the clutch 36. Now, because the pinion 33 is relatively large and the gear 26 is relatively small, the screw shaft is rotated at a relatively high speed in a direction to retract the plunger, so that the retracting movement 1s much more quickly performed than the pressing movement. As the block 73 approaches the retracted position the feeding fingers 90 and 91 are ultimatelymoved into the baling chamber into which loose hay has been inserted, and the hay is forced into the baling chamber ready for the next forward movement of the plunger, any resistance offered 7 by the introduced hay being taken up by the spring 95. After the hay has been introduced. and before the feeder moves into the baling chamber the receptacle 100 is moved to the upright position, so that as the self feeder moves into the baling-chamber a division boardis forced therefrom into thebaling chamber ready to receive the impact of the hay being compressed. When the block 73 has nearly reached the retracted position the stop block 71 is engaged, thus rocking the lever 69 to its first position and causing disengagement of the clutch 36 and reengagement with the clutch 35, so that the pressing action of the plunger begins and proceeds with great power because of its slower movement and greater difference in ratio between the pinion 32 and gear 25 then occurs between the pinion 33 and gear 26. The operations as described continue indefinitely and each charge of hay with its division board passes out of the baling chamber into thecontracted end of the press, where the usual binding parts may be present to provide for the completion of the bales. If, however, the operator wishes to control the action of the press at will, then instead of permitting its automatic continuance, the operator moves the lever 69 by hand to a position throwing out both clutches, whereupon the feed screw stops. It may be started again ineither direction in accordance with the position to which the operator then moves the said lever. By the provision of the adjustable end thrust bearings for the screw shaft much power is conserved for the mesh of the gear teeth may be adjusted with a nicety and at the same time friction due to the thrust is reduced to a minimum by the anti-friction bearings at this point.
